3 .0 mounting instructions
Find a safe place and mount the disconnect where it conve-
niently fits, within clear line of sight and less than 50ft / 15m
from the pump. The product should be fixed using appropriate
screws; ensure you have the correct size for the box sizes. The
conduit / cable should be secured and protected against physi-
cal damage. Make sure the installation follows all local codes
and standards.

KO. Press the edge of a screwdriver against the selected KO's
stamped edge, opposite the point of attachment, and press (or
rap sharply if needed) to push the KO away from the enclosure.
